qt 4.4.3 / eclipse / suse 11.0

Hi,
Cannot debug qt4 apps on suse11.0 with eclipse/gdb.
I have no problems with qt4 apps on suse 10.3 or with c++ apps on suse 11.0. So I assume a qt4/eclipse integration problem.

Launching the app with eclipse stops at "Launching myapp: (87%)"
After a while the following error message is displayed:
gdb Debugger
Error stopping at main
Reason: Target request failed: Target is not responding (timed out)

Running the app without eclipse works fine.

I have suse 11.0 (2.6.25.18)
Eclipse 3.4.1
qt 4.4.3 (qt-eclipse-integration-linux.x86-1.4.3 / gcc4 / 32bit)
java 1.6.0
gcc4

Any idea?
